2-Channel Multiplexer

The TC7WH157 is an advanced high speed CMOS 2-Channel

Multiplexer fabricated with silicon gate CMOS technology.

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation. It consists of 2-input digital multiplexer with

common select and strobe inputs.

When the STROBE input is held “H” level, selection of data is

inhibited and all the outputs become “L” level.

The SELECT decoding determines whether the A or B inputs

get routed to their corresponding Y outputs.

An input protection circuit ensures that 0 to 7 V can be applied

to the input pins without regard to the supply voltage.

This device can be used to interface 5 V to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.

Features

• 5.5-V Tolerant inputs.
